TAPESTRY-GAEPET-SETTING FRAME.

To all whom it may concern:

Be it known that I, CHARLES H. COLLINS, a citizen of the United States of America, residing at No. 10 Jay street, in the city of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Tapestry-Carpet-Setting Frames, of which the following is a specification.

My invention relates to tapestry carpet setting frames, and the object of my invention is to provide a device for causing the threads, of different lengths and tension, in a pattern, to be wound uniformly upon a beam in their proper position as intended by the designer of the figure or pattern; together with such elements and combinations as are hereinafter more particularly set forth and claimed. I accomplish these objects by means of the mechanism illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation. Fig. 2 is a plan. of the clamp wheel.

Similar letters refer to similar parts throughout the several views.

In the manufacture of tapestry carpets the figure or design is printed and wound on large beams before it is put in the loom to be woven. The different processes that the yarn has to go through after being printed makes it impossible to have the different individual ends exactly the same lengths when the pattern is ready to be wound on the beam. This inequality may be caused by the yarn being wet before being printed, or because it is not always dried alike; or the drums on which the yarn is printed may not be exactly the same size; the yarn may be strained while being spooled after being printed; difference in the chemicals may affect the yarn, and other things may operate to thus interfere with the comparative length of the yarn. Because of there being slack and tight ends, it is customary to set the design on a machine called a setting frame, which operation consists of drawing each individual thread into its place so that it will match with the original design. After each thread is set by the operators they are all held in position by a clamp which is mounted on the carriage that travels to and fro on the track or table. On this carriage the design is placed and when the operators set the threads in position they lay them over or on top of the design. After the threads are clamped in position the beam at the Specification of Letters Patent.

head of the machine is started to rotate and in doing so it draws forward the carriage with the clamp attached. It is obvious that the pull of the carriage comes onto the tight or short ends. hen the pattern or design has been wound onto the beam the machine is stopped and another stationary pair of clamps at the head of the machine are closed. Then the clamps on the carriage, which holds the design fast as set, are opened, said operation allowing the operator to push the carriage back to repeat the operation for the next pattern or rug. After each rug or pattern is set the operator must open the front clamp in order to let the yarn wind onto the beam. Under the front clamp is opened, the tight ends have got to do the drawing, and as the slack ends hang at different angles according to their lengths, there is nothing to control them when they are winding onto the beam. The slack ends go on the beam faster than the tight ends which throws the figure out of match.

My improvement over the old setting relates among other things to the stationary clamp at the head of the machine. Instead of the stationary clamp I use a pair of roll ing clamps or clamp rollers, L. These rollers are mounted in the place of the stationary clamps on the setting frame. The great advantage of the rolling clamps over the old system is that they are never opened, which makes it impossible to have the figure go on the beam any different from the way it is set. They hold at all times each individual thread. The rolling clampsperform two very important functions. They prevent the slack ends from coming through onto the beam except at a certain ratio, that is, they hold them back when they would go on too fast and shirr them ahead when they would go on too slow. This may be caused by the construction of the rollers made of iron and rubber, or any other resilient material.

Under the old system the longest lengths set at once are about fifteen feet, while with my improvement any lengthcan be set, it being only a question of longer tracks. It is obvious that this invention will save the For two shot tapestry instance, in an ordinary thirty feet long velvet rug the yarn is about when it is being set. twelve feet long after it has been woven.

This same rug will be this system, after 7 the position shown a a series of, prefer-ably,

The general rule is to set twice in this length, once on the ends and once in the center. It requires no skill to set on the end as there is no design there, only a straight line. But it requires much skill to set in the center, because every thread has got to be drawn in its place over the design. By using my invention it will not be necessary to set in the center at all, as any length of rug can beset on the ends only, it being but a question of longer tracks.

I will now proceed to describe my invention in detail, reference being had to the drawing. On the table, A, I mount a carriage, B, which may run on a rail, C. One end of the carriage is secured to a cable, D which passes over the sheave, E, and pulley, F, and is attached to the pulley bracket, H, and carries the weight, G. The threads, J, are conducted from spools, not shown, under a suitable roller, 7', are connected to the can riage, B, when desired, by means ,of a clamp, K, and pass between the clamp rollers,L, L, and are wound about the beam, M, which is rotated by a suitable mechanism, not shown. I pivot at each side of theta-ble, A, the arms, N, N, as at a, the ends of the arms, N ,N carrying a roller, 0, which rests upon the threads, J, and when the carriage is-in .the position shown by full lines in Fig. 1, that is, at its greatest distance from the clamp rollers, L, L, the arms, N, N, are in in full lines in Fig. 1, the threads passing around the roller, 0. By'dotted lines, I show the position of the arms, N, N, and roller, lO,when the carriage is drawn close to the clamp rollers, L, L. In order to move the carriage back to the position that it occupies, as illustrated in the drawing, the clamp, K, is raised and the weight of the roller, (9, and arms, N, N, causes the arms to fall and draw the yarn or threads to the position shown by full lines; The carriage, B, is pushed back and clamp, K, is then operated to engage the threads and the rotation 0f the beam, M, will wind the threads onto the beam, which will raise the arms, N, N, and draw the carriage. The amount of pull on the-carriage, B, is regulated by the weight, G, and adjustment of the cable.

In order to :provide for taking up the loose yarn or threads, which are drawn out by the operator in order to bring the diiferent portions of the design in proper relation to each other, I have provided the clamp rollers, L, L, which are mounted in a suitable frame, P, one above the other, and between which the threads, J, pass to the beam, M. The rollers are preferably made of metal and the periphery provided with a series of spurs, R, between which are placed 1 rubber strips, 8. The I surface of the rubber strips extends not;

qnite as far from the body of the rollers as'.

do the spurs, B, and when the rollers are placed in the position shown in Fig. 1, the action of the spurs on the threads is to shirr the threads and to take up therefore the slack of the loose threads. The threads which are tight straighten out very quickly after passing between the rollers, while the threads that are loose will retain the shirring and thus the slack will be taken up and the threads will be wound onto the beam evenly with the design and pattern in proper form.

It will be noted that the rotation of :the beam causes the rollers, L, L, to rotate and the action of the threads on the rollers causes their rotation. Because of the roller, 0, and arms, N, N, resting on the threads, J, when the clamp, K, is raised in order to move back the carriage, B, the action of the threads on the reed, not shown, adjacent to the spools, not shown, will be such as to prevent any tangle there and by causing the threads to pass downward from the table around the roller, 0, when in its depressed position, a much shorter track can be used in order'to get the proper length of travel than would otherwise be possible. l

The sheaves, T and U, over which .the threads, 3, pass are suitably mounted on the brackets, t and attached to the table, A.

This improvement is now in practical operation in one of the largest carpet mills in the country, and it makes much better looking work than :the'old system, and increases the production in the setting room as well as in the weaving room, as the yarn goes onto the beam with a more uniformtension, thereby making it run better in the loom.

This improvement is the means of saving many seconds in the setting room.
